Description
Technical Field
The invention relates to a bird damage prevention technology for a high-voltage overhead transmission line.
Background
When the overhead transmission line runs outdoors for a long time, tall and stable line towers are favored by birds and become the first choice for birds to nest and perch, and great threat is brought to the safe and stable running of the overhead transmission line. Birds nest and inhabit on the pole tower, hold conductive foreign matters such as branches, vines and iron wires and stay and shuttle between the wires and the cross arms, so that air gaps are shortened to cause short circuit tripping faults of the overhead transmission line. Birds defecate on a tower, bird droppings with proper viscosity can seriously distort an electric field around an insulator string, so that flashover faults are caused, and meanwhile, the bird droppings are accumulated on an umbrella skirt or a cross arm of the insulator string, so that the insulator string is polluted, flashover occurs, air gap breakdown occurs, and short circuit tripping accidents to the ground or interphase occur.
At present, the common measures for preventing and controlling the bird trouble include bird spikes, bird baffles, bird shields, windmill bird repellers, ultrasonic bird prevention devices and the like, but the effect of preventing and controlling the bird trouble is poor. The bird-preventing stabs can prevent birds from staying on the tower, but the protection range is small, fastening bolts are easy to rust, and steel strands are easy to deform; the bird-proof partition plate can effectively prevent bird droppings from falling, but cannot prevent birds from nesting and inhabiting on the insulator string; the bird prevention cover can prevent bird droppings from polluting the insulator string, but is easily influenced by wind power, poor in stability and easy to fall off; the windmill bird repeller can effectively prevent and control bird damage in the early stage of use, but the windmill bird repeller has the defects of easy aging, short service life, adaptability of birds to the windmill bird repeller after long-term use and the like. The ultrasonic bird repelling device can effectively repel birds, but has the defects of strong directivity, quick attenuation, low reliability, short service life, adaptability of birds caused by long-term use and the like.
Disclosure of Invention
The invention aims to solve the technical problem of providing an overhead transmission line pole tower bird nesting prevention inhabitation discharge device, which can not only achieve the purpose of repelling birds by using bird-proof needling, effectively prevent the birds from nesting and inhabitation on cross arms or insulator strings, but also prevent flashover trip accidents caused by bird droppings falling on the insulator strings by using a bird-proof bottom plate, and ensure the safe and stable operation of a transmission line.
In order to solve the technical problems, the invention adopts the following technical scheme:
the bird nesting prevention inhabitation and discharge device for the overhead transmission line tower is installed on a cross arm of a suspension insulator string and comprises an anti-bird bottom plate and acupuncture points vertically distributed on the anti-bird bottom plate, wherein the acupuncture points are made of conductors capable of discharging, wires electrically connected with the acupuncture points are paved on the anti-bird bottom plate and electrically connected with a power supply, the power supply comprises an electric field energy collecting unit, a rectification voltage stabilizing unit and a storage battery, the electric field energy collecting unit collects high-voltage line coupling energy generated in the environment and converts the high-voltage line coupling energy into electric energy, the electric energy is rectified and stabilized by the rectification voltage stabilizing unit and stored in the storage battery, the storage battery is connected with a high-voltage discharge circuit, and the high-voltage discharge circuit is connected with the wires, converts the electric energy of the storage battery into high-voltage electricity and finally discharges;
the bird detection device is used for detecting whether birds approach the bird detection device, and when the bird detection device detects that the birds approach the bird detection device, the trigger switch is turned on, and the high-voltage discharge circuit is made to discharge.
Preferably, the bird prevention base plate is made of insulating resin or a printed circuit board, and the needling is made of aluminum stranded wires.
Preferably, the distance between the needle pricks is 1-4 cm.
Preferably, the length of the needle-punching is more than 5 cm.
Preferably, the acupuncture distributed on the anti-bird bottom plate has a height difference.
According to the technical scheme, when birds inhabit or nest on the insulator string or the cross arm, the birds cannot nest or inhabit on the insulator string or the cross arm provided with the bird-proof plate due to the blocking effect of bird-proof needling, and the bird-proof plate can actively drive the birds due to the fact that high-voltage line coupling energy generated in the environment is directly collected and converted into electric energy, and high-voltage electricity is discharged through needling. When birds are excreted above the coiled and flying adjacent insulator strings or cross arms, due to the isolation effect of the bird-proof bottom plate, bird droppings are blocked on the bird-proof bottom plate, the bird droppings cannot pollute the insulators or distort electric fields around the insulator strings, and air gap discharge, insulator pollution flashover, and ground or interphase short circuit tripping accidents are avoided.
